自定义帖子类型的永久链接

Question

I am trying to get the link to a custom post type - Video. I have achieved this by doing:

get_post_type_archive_link( 'video' );

This returns http://mylink.co.uk/video which is brillant and exactly what I am looking for. However, when I click onto a custom post type category for example... LIVE and it loads the filtered results, the script link using get_post_type_archive_link( 'video' ); now changes to the LIVE category link showing http://mylink.co.uk/category/live/ .

What is wrong?

UPDATE

function custom_post_type_video() {

    $labels = array(
        'name'                => _x( 'Videos', 'Post Type General Name', 'text_domain' ),
        'singular_name'       => _x( 'Video', 'Post Type Singular Name', 'text_domain' ),
        'menu_name'           => __( 'Video', 'text_domain' ),

    }

I don't know why is it so. I read the code (both yours and WordPress' source code) and didn't find why is it so. I can tell you only two things that might or might not be helpful:-

First

This line:-

register_post_type( 'Video', $args );

should be like this:-

register_post_type( 'video', $args ); // small v

Second

One quick and dirty workaround that you can do is to 'hard-code' the video post type archive link. Try inserting this code in your functions.php:-

function video_post_type_archive_link( $link, $post_type ) {
   if( $post_type === 'video' ) {
      $link = 'http://mylink.co.uk/video' // <-- this should be link to 'video' post type archives
   }
   return $link;
}
add_filter('post_type_archive_link', 'video_post_type_archive_link', 10, 2);

Now, whenever you'll call this:

get_post_type_archive_link( 'video' );

You'll get:

http://mylink.co.uk/video

Only for video custom post type.
